Motor Connections
Connect the motor to the U, V & W
terminals.
The motor earth must be connected
to the drive
Optional Brake Resistor & DC Bus
Connections
Where a Brake resistor is used, it
"BR"
must be connected to the
"+"
terminals.
The brake resistor
should be protected from
overheating by means of a
thermal switch which interrupts
the mains supply in a brake
resistor fault situation.
